CREAM-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 650,537, dated May 29,1900. Application filed September 27,1899. Serial No. 731,837. (Nomodel.)

To (ZZZ whom it may concern.-

Be it known that 1, JAMES M. KING, a citizen of the United States,residing at Nebraska City, in the county of Otoe and State of Nobraska,have invented a new and useful Cream-Separator, of which the followingis a specification.

This invention relates to cream-separators of-that class which employ aliquid agent of lower temperature than the milk to separate the creamtherefrom, and has for one object to provide an improved device in whichthe milk-containing receptacle is fixedly inclosed within the outerreceptacle which contains the cooling agent, whereby the milk-receptacleis maintained in contact with the cooling agent and at the same timepermits of the drawing ofi of the milk and the cream without removingthe milk-containing receptacle.

A further object of the invention is to permit of additional milk beingintroduced into the milk-receptacle without disturbing the cream afterthe latter has been partly or wholly separated from the milk.

To these ends the present invention consists in the combination andarrangement of parts, as will be hereinafter more fully described, shownin the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion,size, and the minor details of construction may be made within the scopeof the appended claims without departing from the spirit or sacrificingany of the advantages of the present invention.

In the drawings, Figure 1 is a longitudinal sectional view of acream-separator constructed in accordance with the present invention.Fig. 2 is a horizontal sectional view thereof, taken on the line m a: ofFig. 1. Fig. 3 is a detail perspective view of the cover for themilk-containing receptacle.

Corresponding parts in the several figures of thedrawings are designatedby like characters of reference.

Referring to the accompanying drawings, 1 designates the exteriorreceptacle, preferably cylindrical in shape, closed at the bottom andopen at the top and adapted to contain water as the cooling agent. Nearthe bottom of the can or receptacle 1 there is provided a drain spout orpassage 2, which is nor mallyclosed by means of a suitable plug 3.Projecting laterally from near the upper end of the receptacle 1 is anoverflow spout or passage 4, through which the water may overflow, so asto prevent intermingling of the water with the milk.

Located within the receptacle 1 is the milkcontaining receptacle or can5, which is preferably cylindrical in shape and is connected to one sideof the receptacle 1. The bottom 6 of the milk-receptacle preferablyinclines downwardly toward the contiguous sides of the two receptacles,and a suitable valve or spigot 7 is located eXteriorly of the outer receptacle near the lower end of the inner receptacle and communicatingwith the inte rior of the latter, so that the contents thereof may bereadily drawn off without removing the inner receptacle. At the point ofcontact of the contiguous walls of the two receptacles the latter areprovided with alined longitudinal slots Sand 9, respectively, and asuitable glass cover 10 is provided upon the outer side of the outerreceptacle, whereby said slots are closed and the interior of the innerreceptacle is exposed to view. A suitable vertical scale may be providedat opposite sides of the glass cover, so as to gage the amount of milkand cream in the inner receptacle. Projecting centrally through thebottom of the inner receptacle is a vertical tube 11, the upperopen endof whichterminates near the top of the receptacle, and the lower openend extends downwardly nearly to the bottom of the outer receptacle.

A dished cover 12 is provided for the up per open end of the innerreceptacle and is provided with a short central tube 13, which isadapted to fit within the open upper end of the tube 11, so as to permitof water be ing poured into the dished or funnel-shaped cover andconveyed therefrom centrally through the inner receptacle and dischargedinto the outer receptacle. Located at one side of the tube orfunnel-spout 13 is another upright tube 14, fixed to the cover 12 andprojecting both above and below the same, the lower open end of saidtube terminating close to the bottom of the inner receptacle, and ispreferably arranged near the lowest portion thereof.

In the operation of the device the milk is introduced into the innerreceptacle through the milk-inlet tube 14, and the water, which is oflower temperature than the milk, is poured 5 into the outer receptacleeither through the funnel-shaped cover 12 or through the open top of thereceptacle 1 at one side of the inner receptacle. After the desiredquantity of milk has been placed in the device the upper open end of themilk-inlet tube let is closed in any suitable manner, so as to preventingress of dirt or other foreign matter.

By reason of the difference in temperature between the water and themilk the cream :5 .will be separated from the latter and rise to thesurface thereof, this separation being conveniently discernible throughthe glass- .covered slots 8 and 9. After the separation has taken placethe milk is first drawn off 2'0 through the spigot 7, the glass cover 10permitting of the operation being observed, so .as to prevent mixing ofthe milk and cream, as will be readily understood. It is preferable topour the water through the central tube 11, as the cooling effect of thewater is had at the center of the milk as well as upon the exteriorthereof, although this tube may be dispensed with, as desired. After thefirst introd notion of milk other milk may be poured 3o into the innerreceptacle, as such milk will be discharged from the inlet-tube 14 at apoint near the bottom of the receptacle,whereby the cream upon thesurface of the milk will not be agitated or otherwise affected. 5 It ispreferable to incline the bottom of the ,inner receptacle toward thecontiguous sides of both receptacles, so that the valve orspigot 7 maybe conveniently located at the lowest point of the milk containingreceptacle,whereby the contents of the latter maybe entirely ,drawn off,as will be, understood. Also the lower discharge end of the milk-inlettube 14 is preferably located as near as possible to p the lowestportion of the bottom of the inner 45, receptacle, so that the milkwhich is added to that already in the receptacle will be discharged atthe lowest point, so as not to disturb the cream, as hereinbefore setforth.

What I claim is- 1. A cream-separator, comprising an outer receptacle aninner rece tacle havin a tube receptacle, and an inner receptacle havinga dished top or cover, a tube communicating with an opening formed inthe top or cover and also opening into the interior of the outerreceptacle, a milk-inlet tube extending through the top or cover, andmeans for drawing off the liquid contents of the inner receptacle,substantially as shown and described.

3. A cream-separator, comprising an outer receptacle, and an innerreceptacle having a vertical tube projecting in opposite directionsthrough the bottom thereof, a removable funnel-shaped cover having itsspout communicating with the upper end of the tube, and also a verticaltube extending in opposite directions through the cover, and means fordrawing off the liquid contents of the inner receptacle, substantiallyas shown and described. I

4. A cream-separator, comprising an outer receptacle, an innerreceptacle fixed to one side of the outer receptacle and spaced abovethe bottom thereof, the contiguous sides of both receptacles beingprovided with vertically-alined and glass-covered slots, a central tubeextending in opposite directions through the bottom of the innerreceptacle, a removable funnel-shaped cover for the inner receptacle,the spout of the cover communicating with the upper end of the centraltube, a vertical tube extending in opposite directions through the coverand terminating at its lower end near the bottom of the innerreceptacle, and a Valve or spigot located exteriorly of the device, nearthe lower end of the inner receptacle, and communicating with theinterior of the latter, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
